In order to give the t'z'tbliit 20 th required step by step orintermittent partial wh rotation neeessary to temporari y carry thevarious knohs or mounts successively into the holds of action of thevarious rotating butler wheels, I provide a pinion 68 (Fig: 9) on theinner end of a. main dri ing shalt (it) 7 with a driving pulley Tl.

The periphcry of plate 86 is provided with tour (firlH'zl-Yh ties 87 ofthe same diameter as and, adapted to receive portimis of the hub Stadepending from the plate wherehv to lei-la the plate 86 in properpositions 90 apart.

In :der to couple or clutch the gear 78 to the plate 83, whereby tocause the intermittent 90 rotation of the plate 86 and shaft 23, Islidingly mount on the stationary shaft 70 a clutch sleeve 89 having adowmvarrllyextended pin 90 passing through an aperture in the gear 78and adapted to be projected into an aperture 91 of the roller .plateB-l.As obvious, when the sleeve 80 slid down on. the shaft 79 the in. 00looks togevher the gear and late 83 by passing through apertures in th.To actuate and slide this rotary sleeve 89 vertically on the shaft 70, Iemploy a lever 92 fulcruincd at 93 and having the usual arms straddlingthe sleeve 80 and supplied with projections entering a circular groove95 thereon. Since this is a usual and ordinary construction, further(lo-- scription of its details is not deemed necessary. The lever 92 isnormally pulled up wardly by a spring 96 and has at its outer on d aroller 97 adapted to ride upon. the periphery of a cam 98 mounted on andfastened to the cam shaft 7 2. It should be apparent from thisdescription and ope 'ation of the parts that, owing to the rotation. ofthe cam 08, the lever is at times rocked upon its fulcrum 93 so as toraise or lower the sleeve and the roller plate 83, causing the periodsof move ment and idleness thereof. The hub S8 of the late 83 has aconcave portion or recess At its outer end each arm of the spider issun-' 99 Pig. 9) opposite the roller 84, and during the rotation of theplate 83 and its hub 88, and as the pin or roller 84 enters one ol theslots 85, the plate 86 is unlocked and permitted to have rotary movementtransmitted thereto by the pin or roller 84-, due to the fact that therecess 99 of hub 88 comes to such a position as to cause the unlocking,the external convex surface of the hub normallylitting in one of theconcavities 87 of ;derstood that the plate 86 and shaft 22 are unlockedand turned each time that the cam 98 permits such movement of the parts.

Referring now to the inecl'ianisin for rotating the shafts 67 and knobsor mounts 00 on their own axes, it Will be noted that the mainhorizontal driving ulley 100 (Fig. 12) o aerated by a belt 101 ig. 2) iskeyed to a s eeve or bushing 102 rotatable on the hollow shaft or 0st35, a-central friction drive pulley 103 eing also keyed to the sleeve orbushing 102and operated. by the belt 101, as is obvious.

011 a light-angle bracket or support 214 there is placed a guide 2315,grooved internally at 216 to accommodate outwanlly-erotended flanges orguides 217 on the outer faces of the side Wheels 218 of e carriage orsupport for a block or bar 01 ebfiading or polishing material 2' 9.zleross the top ol these side wheels a oover 220 is extended againstwhieh the bar of ubntdnnt or polishingunltoriz. l 's prl "sod by a pairoi right angle bloeh's 2321 p11. *l upwardly by ooil springs The end ofthis carriage or support from the boiler wheel, as showi'l in Fig. 12%,is open. and the bloel; oi abradant or polishing material irojeots outol. the same toward the whee, as will be reedily uiulerstood. lllxtendedlongitudinally of this :bradant llOli. and between the bloc 221, itprovide a screw-tinnailed. rod L23, which has 5 bearing in a plate Lclosing the outer end of the box, and is revontel'l from longitudinalting in snob. bearii'ie; by suit able collars or other urts, me of thecol being oharzuzterirzecl i225. Uri this sereutl'irendod rod is 2threaded out 3525 adopted to bear against the reel end of the bloelc;ol' abrzulant or polishing .luuterial 211.9 and littine; between theMills of the carriage orsuuport so as to prevent rotation oi the not 'llherelore, as the rod or zj rew is turned the nut is mused to trove:l'oru zirdly' or rearimrdly in zuzmirdanee with the direction ofrotation ol' the screw, and when thus .i ul lorwardly the biopic ofahriulaut material is caused to projeet farther out ol the open end ofthe rarriage. rail-[hot is lixed to the snow 2123 just outside of theend plate 224;, and rotatable on the round portion oi the screw outsideor next to the ratehot i provide a toothed segment 225* having;onpositelytended arms 2329 and 230, the former havirug; pivoted there;-at 22 l a spriug-pressml pawl eolnenting with the teeth of thezu'ljiusent rutehetilil'i.

Segment 2412 has on uprcarilly-externlml arm ill?) towhich is pivoted a spriruggz.etuulwl pawl 2 -1- 1 (rd-noting with. theteeth of the ratehet The arm M3 is also roi-ineotml to a pin secured tothe opposite side of the varriage by a contractile spring 2415 which isadaptei'l, under normal conditions, to hold the meshing segments in theposition shown in Fig. 16.

it is to be understood that as the box or carriage with the block or barof abradant or polishing material is advanced by a downward pull on thechain 239 so as to apply the abradant or polishing material to thebuffer Wheei, the arm or finger 2"() of the segment 228 is shifted toone side by the cam surl'ace 233, causing the intermeshing segments torotate in opposite directions on their respertive shafts or screws 223and During this movement of the segments the pawls 232 and 2&4 byeo-action with their ratchets fixed to the screws cause a partialrotation of the screws in opposite directions, thereby advancing the nutor block 226 so as to project or advance the bar or block of abradant219 a small amount to compensate for the Wearing oll' ol the barabradant b its successive contacts With the periphery of the butlerWheel. The other nut 238 is slightly by the partial rotation of itsscrew 237, whereby to modify the travel of the carriage and the abradantbar to make up or compensate for the Wearing down of the buller wheel.in. other words, the turning I of the screw 237 changes the point ofconnection of the chain 239 with the carriage which 'itslides so thatthe arrriage travels slightly farther forwardly on each in'\ ardmovement.

To draw back or retract the abradant rarriago or support, I employ acoil spring 245 connected at one end to a pin 245 on the side oi" thecarriage, and at its other end to an out orally-extended arm 245suitably supported on and connected to q uide block 215.

The chain 2") connected the abradant applying means for the butler Wheel27 is connected by means of a rod'2 l6 to the front end of an arm orlever 247 (Fig. 2) lulcriimed on the base at 248 and carryingintermediate its ends a roller 249 riding on the cam periphery of a earn250 on cam shaft 72.

The chain 239 for the abradant applying mechanism for the bul'ler Wheel28 (Fig. at) is connected by a rod 251 to a rock arm 252 having ahearing at 253 and supplied with a roller co-aeting with a ram 255 oncam shaft 72. .r

The actuating chain. 239 forthe abradant applying mechanism used inconnection with the butler wheel 29 (L 1 and iii coi'meeted to the endof a rocker arm fulcruined on the base of the machine at 257' and havinga roller 258 traveling on the edge of still another cam 259 fixed to androtatable with cam shalt 72.

'lhe operation of this machine is substantially as follows: Assumingthat the table 20 carrying the plurality of brackets and knobssupportedthereby has just completed one of retracted its 30 partialrotations, the cams herein before describwl act upon the three slides 38opposite the buil'er wheels 27, 2S and. 29 to push them outwardly inopposition to their springs to so as to bring the knobs against theperipheries of the buii'er heels. 'l'hese knobs are rotated on their ownaxes, due to the contact of the three lrietiou pulleys 110 with thecentral driving pulley 103, the retation of the smaller pulleys 110being trans-- mitted, as will be obvious, to the knobs through theflexible shafts (i7 and the intermeshing gears 62% and (5].. While thehue )S are being burnished or polished by the bulie wheels they are alsoswung laterally or on axes other than their own, that is the axes oi thevertical short shal'ts -l-T by the "aims described ahove and theconnecting inechanisms. These cams niaybeso proportioned and shaped asto have the various butler Wheels operate for dili'rreni. piuiods ol' tion the dillerent portions oi' the knobs. example, owing to thecontraction and dr-- m in of the metal at the base ol the i" there ismore tendency lor inequalities, grooves, and sci ilt'lltb to be presentthere, and conseipiently it may be niore desirable to have the .lirstbutter \rhrel Z27 art tor a much greater time on t he nerli or shank olthe luioh than on the head proper. 'l'hi-se rains coin trolling theswinging ot' the knobs may, of course, be made in any shape desired, andthe swinging or turning of the three knobs in .l'ront of the threebutler wheels may Vary considerably. During such action, howewir, theknob continually turns on its own axis regardless of its swinginglaterally. a
